ABSTRACT

A multi-functional cargo area assembly for a cargo bed of a vehicle includes a first and a second side wall disposed in a transversely spaced relationship, and an integrally formed guide track in the first and second side walls. The cargo area assembly also includes extendible side wall portions. The cargo area assembly further includes a movable divider panel supported with the guide track by a support rod, and extending transversely between the first and second side walls, wherein the divider panel includes a positioning mechanism for fixedly locating the divider panel.

FIELD OF THE INVENTION

The present invention relates generally to a cargo bed liner for a vehicle, such as a pickup truck or a sport utility. More specifically, the invention relates to a multi-functional cargo bed liner assembly for the cargo bed portion of a vehicle, which functions to extend the length of the cargo bed and includes an infinitely positionable divider panel.

BACKGROUND OF THE INVENTION

Utility vehicles, such as pickup trucks and cargo vans are characterized by a load carrying portion, referred to as a cargo bed, defined by a generally planar floor. The dimensions of the cargo bed vary in length from several feet to more than eight feet. These types of vehicles are multifunctional, since they satisfy both transportation and load carrying capacity needs.

Various devices are available to further increase the versatility of the utility vehicle, and in particular the cargo bed portion. One example of such a device is a cargo bed cover for enclosing the cargo bed of a pickup truck. Another example is a removable cargo bed liner, which is configured with the shape of the cargo bed, to protect the surface finish of the cargo bed. Still another example is a cargo bed divider, for subdividing the cargo bed of the pickup truck to accommodate diverse, or various sized, loads. The prior art has implemented a number of different approaches towards providing cargo bed dividers for pickup trucks. Some prior art dividers are shown in U.S. Pat. Nos. 5,411,355; 4,722,646; 5,603,439; 5,456,514; 5,423,463; 5,415,506; 3,767,059; 5,044,682; 4,733,899; 5,265,993; 5,586,850; 5,628,442; 5,845,953; 4,834,599; 5,259,712 and 5,927,783. At the same time, it is also advantageous to expand the volume of the cargo bed of a pickup truck to accommodate an oversized load, such as a 4×8′ sheet of plywood.

While various of the prior art cargo bed liners and divider systems referenced herein are reconfigurable, none of these systems allow for the expansion of the interior volume of a pickup truck's cargo bed. Thus, there is a need in the art for a multi-functional cargo bed liner assembly that is expandable and includes a divider panel that is infinitely positionable.

SUMMARY OF THE INVENTION

Accordingly, the present invention is a multi-functional cargo area assembly for a cargo bed of a vehicle. The cargo area assembly includes a first and a second side wall disposed in a transversely spaced relationship, and an integral guide track formed in the first and second side walls. The cargo area assembly also includes an end wall extending between the first and second side wall at a first end, and a floor extending between the first and second side walls. The cargo area assembly further includes a movable divider panel supported within the track by a support means, and extending transversely between the first and second side walls, wherein the divider panel includes a positioning mechanism for fixedly locating the divider panel.

One advantage of the present invention is that a multi-functional cargo area for a vehicle is provided that includes a divider panel which can be positionally fixed at infinite locations within the cargo bed, so as to subdivide the cargo bed into a plurality of separate areas. Another advantage of the present invention is that the divider panel can articulate and be fixed in a horizontal position, to provide a work surface. Still another advantage of the present invention is that the divider panel can be stowed near the front of the vehicle when not in use. A further advantage of the present invention is that a side wall and the divider panel can be extended out onto a lowered tailgate of the vehicle, to increase the length of the cargo bed. Still a further advantage of the present invention is that the side wall includes an integrated track for repositioning the divider panel. A further advantage of the present invention is that multiple accessories can be utilized in combination with the multi-functional cargo area assembly to further increase the functionality thereof.

Other advantages and features of the present invention will be readily appreciated as the same becomes better understood after reading the subsequent description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

The multi-functional cargo bed assembly 10 of the present invention is operable to subdivide the cargo bed of a utility vehicle, such as a pickup truck, into a number of separate areas. It is further operable to extend out onto the lowered gate of a pickup truck to expand the volume of the cargo bed. Most preferably, the extension sections and divider panel fully enclose the sides of the cargo bed when the panel is extended out onto the lowered tailgate.

Referring to FIGS. 1-7, a multi-functional cargo bed liner assembly 10 for the cargo bed portion of a vehicle (not shown), which in this example is a pickup truck, is illustrated. The cargo bed liner assembly 10 has a general box-like shape. The cargo bed liner assembly 10 includes a generally planar floor portion 12, forming the floor of the cargo bed liner 10. The cargo bed liner assembly 10 also includes an end wall 14 extending from an end of the floor 12, adjacent the cab of the vehicle. Preferably, both the floor 12 and end wall 14 include a plurality of integrally formed ribs 16. The ribs 16 are spaced a predetermined distance apart, and extend longitudinally. Advantageously, the ribs 16 provide structural support to the floor 12 and end wall 14, respectively.

The cargo bed liner assembly 10 further includes a side wall 18 extending upwardly from a side edge of the floor 12. In this example, the cargo bed liner assembly includes a first side wall 18 a disposed in a transversely spaced relationship with a second side wall 18 b. The side wall 18 includes a fixed side wall 20 with a side extension wall 22 slidably attached to the fixed side wall 20. It should be appreciated that the fixed side wall 20 is generally planar, and a first side edge of the fixed side wall 20 is adjacent to the end wall 14, and a second side edge of the fixed side wall is unattached, as shown at 24. The fixed side wall 20 and side extension wall 22 may include an integrally formed feature as shown at 26 such as a depression or boss or the like. In particular, the integrally formed feature 26 enables the cargo bed liner assembly 10 to conform with the shape of the cargo bed portion of the vehicle.

In this example, the unattached edge 24 of the fixed side wall 20 includes an integrally formed depression having a rectangular shape, as shown at 28, to provide access to a positioning mechanism 30, for positioning the side extension wall 22 with respect to the fixed side wall 20 in a manner to be described. A lower portion of the fixed side wall 20 includes an integrally formed groove extending longitudinally, to provide a lower track 32 for slidably positioning the side extension wall 22. Preferably, the length of the lower track 32 corresponds to the distance of travel required for the side extension wall 22. As shown in FIG. 6, the lower track 32 also includes a portion extending radially a predetermined distance from the lower track 32 to form a locking groove 34, for locking the side extension wall 22 in a desired position, in a manner to be described.

A lower portion of the fixed side wall 20 includes a plurality of integrally formed, vertically extending indexing grooves 36 spaced a predetermined distance apart, extending longitudinally there along the fixed side wall 20 a predetermined length, for indexing the position of a divider panel 38 of the cargo bed liner assembly 10, in a manner to be described. In this example, the lower portion of the fixed side wall 20 includes a plurality of indexing grooves 36, and a recess 26 that conforms with the shape of the wheel well portion of the cargo bed. Also in this example, an upper portion of the fixed side wall 20 includes an integrally formed storage box 40 having a cover, for storing items within. In addition, a lower edge of the upper portion of the fixed side wall 20 forms a lip, to provide an upper track 42 for guiding the movement of the side extension wall 22. The fixed side wall 20 also includes a slot 44 extending longitudinally between the upper portion and lower portion of the fixed side wall 20, to provide access to a track for the divider panel 38.

Advantageously, the side extension wall 22 increases the overall length of the cargo bed of the vehicle. It is contemplated that the side extension wall 22 may be a single panel, or an assembly. In this example, the side extension wall 22 is an assembly and includes an inner panel 46 joined to an outer panel, 48 to form a unitary wall, having a box-like shape. The outer panel 48 is a generally planar member. The outer panel 48 includes a lower flange 48 a extending from lower portion of the outer panel 48 to form a lower guide for the side extension wall in the lower track 32 in the fixed side wall 20. The outer panel 48 also includes an upper flange 48 b extending from an upper edge of the outer panel 48, to form an upper guide for the side extension wall 22 with respect to the upper track 42 formed in the fixed side wall 22.

A lower portion of the outer panel 48 further includes a plurality of vertically extending indexing grooves 50 spaced a predetermined distance apart, similar to the grooves 36 in the fixed side wall 20, for positioning the divider panel 38. The outer panel 48 further includes a longitudinally extending slot shown at 52 positioned above the indexing grooves 50 in the outer panel 48. It should be appreciated that the slot 44 in the fixed side wall 20 and slot 52 in the outer panel 48 form a single slot, to allow unencumbered travel of the divider panel 38. The outer panel 48 may include a cutaway portion (not shown) at en end of the slot 52, for removing the divider panel 38 from the cargo bed liner assembly 10.

The inner panel 46 is also a generally planar member. In this example, the inner panel 46 includes a longitudinally extending channel shown at 54 having a box-like shape. Advantageously, the inner panel 46 and outer panel 48 can be formed and joined as one using a conventional technique, such as blow molding.

Referring to FIGS. 5-6, the side extension panel further includes a locking mechanism 56, for retaining the side extension wall 22 in a fixed position relative to the fixed side wall 20. The locking mechanism 56 is slidably disposed between the inner panel 46 and outer panel 48 of the side extension wall 22. Preferably, an outer edge of the outer panel includes a recess, shown at 57, to provide the operator access to the locking mechanism 56. In this example, the locking mechanism includes a handle 58 for actuating the locking mechanism 56 to position the side extension wall 22 with respect to the fixed side wall 20. The handle 58 includes a generally planar face, with a rectangular recess shown at 60, for receiving the fingers of the operator in locking and unlocking the side extension panel. A lower portion of the handle 58 includes an integrally formed locking tab 62 having an “L” shape. The locking mechanism 56 further includes a biasing spring (not shown), such as an extension spring disposed in a recess (not shown) formed above the handle 58. Preferably, the spring is secured at one end to the handle 58 and at the other end to the side extension wall 22, to bias the handle in a locked position

The cargo bed liner assembly 10 includes a tailgate panel 64 fixedly attached to the tailgate (not shown) of the vehicle using a conventional fastener, such as a screw. The tailgate panel 64 is a generally planar member, and includes a plurality of integrally formed ribs 66 spaced a predetermined distance apart, to provide structural support to the tailgate panel 64. The tailgate panel 64 also includes an integrally formed groove forming a track 68 for positioning the side extension wall 22 relative to the fixed wall. The groove has an “L” shape, with the smaller leg forming a locking groove as shown at 70, and similar to the locking groove 34 for receiving the locking tab 62 of the locking mechanism for retaining the side extension wall 22 in a fully extended position.

To operate the locking mechanism 56, the operator grips the handle 58 by placing the fingers in the recessed area 60 of the handle 58, and raises the handle 58 to overcome the force of the biasing spring to disengage the locking tab 62 from either the locking groove in the fixed side wall 20 or tailgate panel 64. It should be appreciated that the force of the biasing spring on the handle 58 retains the locking tab 62 in the preferred locking groove 34 or 70. Then, the operator slidably extends or retracts the side extension wall 22 to a predetermined position, aligns the locking tab 22 with the locking groove 34, 70 and releases the handle 58 so that the force of the spring retains the locking tab 62 in the locking groove 34, 70. In this example, the predetermined position is either at the end of the tailgate panel 64, or at the end of the fixed side wall 20. It should be appreciated that the side extension wall 22 effectively extends the length of the sides of the vehicle.

As shown in FIG. 3, the cargo bed liner assembly 10 includes a frame 72 for supporting the cargo bed liner assembly 10. The frame 72 includes an inner track 74 slidably disposed within an outer track 76 and supported by legs 78. Preferably, the legs 78 are mounted to the vehicle using a conventional fastening means, such as a bolt or screw. In this example, the inner track 74 has a “C” shape and the outer track 76 has a “U” shape. The inner track 74 and outer track 76 can be extruded from a material such as steel or plastic. The frame 72 extends along the length of the side wall 18. Preferably, the inner track 74 includes a gear track 75 disposed therein for indexing the travel of the divider panel 38 in the inner track 74. In this example, the gear track 75 includes a plurality of tooth-shaped members, as is known in the art, although other types of gear tracks 75 are contemplated. The side wall 18 is attached to the frame 72 using a conventional fastening mechanism, such as a bolt. In this example, the fixed side wall 20 is securely mounted to the outer track 76, and the side extension wall 22 is securely mounted to the inner track 74. Preferably, the height of the legs is selected so that the inner track 74 and outer track 76 are accessible through the slot 44, 52 extending therethrough the fixed side wall 20 and side extension wall 22.

Preferably, the frame 72 is disposed inboard of the wheel well (not shown) of the vehicle. This mechanical arrangement is not necessary; however, by so disposing the frame 72, it is assured that the divider panel 38 will clear the wheel well without the need to have any type of cutout or the like which could compromise its integrity.

The cargo bed liner assembly 10 includes a divider panel 38 that can be moved along the inner track 74 to a number of different positions, so as to permit the cargo bed to be subdivided into separate areas. As illustrated in FIG. 2, the panel 38 is shown in a first position A and a second position B, also within the cargo bed, as shown in phantom outline. In addition, the panel 38 can be moved atop the lowered tailgate, as shown in FIG. 1 at 80. Advantageously, when the divider panel 38 is in the position shown at 80 with the side extension wall 22 fully extended, the effective length of the cargo bed is increased. Further, the divider panel 38 can be removed from the cargo bed assembly 10 through the cut-away portion.

Referring to FIG. 4, the divider panel 38 includes a pair of generally rectangular panels 82 arranged parallel to each other, and a side panel 84 interconnecting the pair of panels 82. The divider panel 38 includes a positioning mechanism 30, to be described, disposed between the panels 82, 84, for fixedly retaining the divider panel 38 in the inner track 74. The panel 82 may include a cutout handle portion shown at 86 to aid in its repositioning.

In some embodiments of the present invention, the divider panel 38 may be configured so as to be pivotable in the inner track from a position wherein it is generally perpendicular to the floor 12 of the cargo bed assembly 10, to a position wherein it is parallel to the floor 12 so as to provide a table or work surface. In such instances, it may be advantageous to include within the panel 82 an integrally formed feature providing a cup holder, shown at 88. Similarly, panel 82 can be configured to include other features such as slots, as shown at 90, or small diameter openings (not shown) for holding work pieces or the like. Advantageously, manufacturers' logos and the like may also be incorporated into the divider panel 38 (not shown). Most preferably, the divider panel 38 is fabricated from molded polymeric material, although sheet metal, composites and the like may be similarly employed.

In FIG. 4, the divider panel 38 is illustrated in operational relationship to the frame 72 and vehicle. As shown, the divider panel 38 is supported within the inner track 74. The divider panel includes a support means 92 that provides support and movement of the divider panel 38 within the inner track 74. In this example, the support means 92 is a rod 94 extending longitudinally, with a wheel 96 attached to each end of the rod 94. The rod 94 is rotatably supported by the panel 82, such as by a hook 98. Preferably, the wheel 96 includes a gear 95, as is known in the art, for indexing the travel of the wheel 96 in the inner track 72. Advantageously, the indexed rolling motion of each wheel provides for uniform motion of each wheel, and avoids slipping and binding. It should be appreciated that the wheels 96 may include bearings and the like, as is understood in the art, to facilitate the rolling motion of the wheels 96 along the inner track 74.

As further illustrated in FIG. 4, the positioning mechanism 30 associated therewith for fixedly positioning the divider panel 38 is illustrated. Preferably the positioning mechanism 30 is disposed between the panels 82. The positioning mechanism 30 includes a handle 100 disposed within the handle cutout 86 for positioning the divider panel 38. The latching mechanism 30 also includes a stabilizing block 102 extending therethrough an opening in the side panel 84, and operatively connected to the handle 100. In operation, the stabilizing block 102 is rigidly engaged within the indexing groove 36, 50 in the side wall 18, to fixedly retain the divider panel 38 in a predetermined position. Preferably, there are two opposed stabilizing blocks 102.

In this example, the positioning mechanism 30 includes a center lever 104 that pivots about a fixed point, preferably in the center of the panel 82. The handle 100 is also a lever that pivots about an upper pivot point. It should be appreciated that in this example, there are two handles 100, with each positioned at an upper corner of the panel 82. Further, the center lever 104 and handles 100 are pivotally attached to the panel 82, such as by using a bolt 105. The positioning mechanism 30 further includes a means 106 for interconnecting the center lever 104 with the handles 100, such that in operation depressing the handle 100 actuates the center lever 104 to retract the block 102, so that the divider panel 38 can be repositioned. Preferably, the interconnecting means 106 interconnects a free end of one handle 100 with an end of the center lever 104, and an other end of the center lever 104 with the block 102. Similarly, another interconnecting means 106 connects the other handle 100 with the center lever 104. It is contemplated that the interconnecting means 106 is a rod or wire or the like. The positioning mechanism 30 also includes a biasing spring 108 fixed at one end to the block 102, and at an other end to the panel 92, so as to position and lock the block 102 within the indexing grooves 36, 50.

In operation, depressing one of the handles 100 causes the handle 100 to pivot upwards and the center lever 104 to pivot, which in this example is in the counterclockwise direction, thus retracting the block 102. In this example, depressing either handle 100 will cause both blocks 102 to simultaneously retract, so that the divider panel 38 can be repositioned. In addition, the divider panel 38 rolls along the track 74 at a uniform rate without slipping or binding, since the travel of the wheel 96 within the track 74 is indexed. Advantageously, the operator can reposition the divider panel 38 using one hand.

It is to be understood that the foregoing drawings, discussion and description illustrate particular embodiments of the present invention. Yet other modifications and variations thereof will be readily apparent to one of skill in the art. For example, as mentioned above, the divider panel 38 may be configured so as to be pivotable through at least 90° of rotation. This will provide for ease of access to the cargo compartment, and will permit the divider panel 38 to be used as a worktable, dining table, seating surface or the like. In such instances, folding legs or other such supports may be associated with the divider panel 38. The system of the present invention may be fabricated form a number of materials including metals, polymers, composites and the like. In some preferred embodiments, the frame 72 will be fabricated from high strength engineering polymers such as nylons, reinforced polymers and the like. In other instances, the frame 72 is most preferably fabricated from metal.

Referring to FIGS. 8 and 9, another embodiment of a multifunctional cargo bed liner assembly 210 with an integral track is illustrated. It should be appreciated that like features have like reference numerals increased by 200. In this embodiment, the fixed side wall includes an integral track 312 for positioning the divider panel 238, and the assembly 210 is self-supporting. The cargo bed liner assembly 210 includes a generally planar floor portion 212, forming the floor of the cargo bed liner assembly 210. The cargo bed liner assembly 210 also includes an end wall 214 extending from an end of the floor 212, adjacent the cab of the vehicle. Preferably, both the floor 212 and end wall 214 include a plurality of integrally formed ribs 216, as previously described. The ribs 216 are spaced a predetermined distance apart, and extend longitudinally. Advantageously, the ribs 216 provide structural support to the floor 212 and end wall 214, respectively.

The cargo bed liner assembly 210 further includes a side wall 218 extending upwardly from a side edge of the floor 212. In this example, the cargo bed liner assembly 210 includes a first side wall disposed in a transversely spaced relationship with a second side wall. Each side wall 218 includes a fixed side wall 220 and a side extension wall 222 slidably attached to the fixed side wall 220. It should be appreciated that the fixed side wall 220 is generally planar, and one side edge of the fixed side wall 220 is adjacent to the end wall 214.

The fixed side wall 220 or side extension wall 222 may include an integrally formed feature, such as a depression or boss or the like. For example, the fixed side wall 220 includes an integrally formed depression, shown at 226, that provides a storage compartment for the cargo bed liner assembly 210, in a manner to be described.

A lower portion of the fixed side wall 220 includes an integrally formed groove extending longitudinally, to provide a lower track 232 for slidably positioning the side extension wall 222, as previously described. Preferably, the overall length of the lower track 232 corresponds to the distance of travel required for the side extension wall 222. The lower track 232, as well as an upper mating engagement between the fixed side wall and the side extension wall, allow the side extension walls 222 to slide relative to the fixed side walls 220 without the requirement of additional frame/track structure as utilized in the embodiment of FIG. 3. The lower track 232 also includes a portion extending radially a predetermined distance from the lower track 232 to form a locking groove (not shown), for locking the side extension wall 222 in a desired position, as previously described.

The fixed side wall 220 includes a lower section 220 a, an upper section 220 c, and a midsection 220 b formed therebetween the upper section 220 c and the lower section 220 a. The lower section 220 a includes an indexing portion shown at 221, extending longitudinally there along the fixed side wall 220 a predetermined length, for indexing the position of a divider panel 238 for the cargo bed liner assembly 210, as previously described. The indexing portion 221 includes a plurality of integrally formed, vertically extending, indexing grooves 236 spaced a predetermined distance apart. The lower section 220 a of the fixed side wall 20 also includes an integrally formed depression 226, which preferably conforms with the shape of the wheel well portion of the vehicle cargo bed.

The midsection 220 b of the fixed side wall 220 includes an integrally formed channel 314 extending longitudinally between the upper section 220 c and the lower section 220 a of the fixed side wall 220. The channel 314 is oriented on a horizontal plane between the upper section 220 c and the lower section 220 a. Preferably, the channel 314 is U-shaped.

The upper section 220 c of the fixed side wall 220 advantageously provides a storage area, as shown at 240 for storing items within the cargo bed liner assembly. The upper section 220 c of the fixed side wall 220 includes a generally planar back wall 214, and a separable front wall 243. The back wall 214 extends upwardly from the midsection 220 b of the fixed side wall 220. Preferably, the back wall 214 is molded to conform with vehicles having side walls of various shapes. The front wall 243 includes an access opening shown at 245 for providing access into or out of the storage area 240. Preferably, a door 247 covers the access opening 245, and articulates to provide ingress and egress to the storage area 240.

In addition, a lower edge of the front wall 243 forms a lip 249. The front wall 243 also includes a longitudinally extending flange 251 extending downwardly from an edge of the lip 249, and having an “L” shape. The lip 249 and flange 251 cooperating form a portion of the integral guide track 312 for guiding the movement of the divider panel. The vertical extending face of the flange 251 includes a longitudinally extending slot 244 for positioning the side extension wall 222 relative to the fixed wall 220 in a manner to be described. The front wall 243 and rear wall 214 are joined together to form an integral structure.

Advantageously, the side extension wall 222 increases the overall length of the cargo bed of the vehicle. It is contemplated that the side extension wall 222 may be formed as a single panel, or an assembly. In this example, the side extension wall 222 is an assembly and includes an inner panel 246 joined to an outer panel, 248 to form a unitary wall, having a box-like shape, as previously described.

The outer panel 248 is a generally planar member, and includes a forward section 253 and a rearward section 255. The forward section 253 is a partial wall, and does not extend all the way to the floor 212 of the cargo bed liner assembly 210. The rearward section 255 is a full wall and extends all the way to the floor 212 of the cargo bed liner assembly 210. The rearward section 255 includes a lower flange 248 a extending from a lower edge that forms a lower guide for the side extension wall 222 in the lower track 232 in the fixed side wall 220.

The side extension wall 222 also includes an upper flange 248 b extending from an upper edge, that forms an upper guide for the side extension wall 222 with respect to the fixed side wall 220. In this embodiment, the upper flange 248 b has an inverted “L” shape. The upper flange 248 b includes at least one outwardly projecting guide means 257 disposed therein. An example of a guide means 257 is a fastener, such as a bolt or screw or the like, although other types of guides are contemplated. The guide means 257 includes a head portion that is movably engaged within the guide slot 244 in the securing flange 251. In operation, the guide means 257 travels within the guide slot 244 to locate and position the side extension wall 222 relative to the fixed wall 220.

The outer panel 248 further includes a plurality of vertically extending indexing grooves 250 spaced a predetermined distance apart, similar to the grooves 236 in the fixed side wall 220, for positioning the divider panel 238. It should be appreciated that an upper end of the indexing grooves forms a gear track 275 for indexing the position of the divider panel, while the vertically extending depression between consecutive indexing grooves 250 lock in the indexed position of the divider panel 238.

Preferably, the outer panel 248 includes a cutaway portion (not shown) for removing the divider panel 238 from the cargo bed liner assembly 210 in a similar manner as previously described.

The inner panel 246 is also a generally planar member, and provides a rear wall and structural support to the side extension wall 220. Advantageously, the inner panel 246 and outer panel 248 can be formed and joined as one using a conventional technique, such as blow molding. The side extension panel further includes a locking mechanism 256, as previously described.

It should be appreciated that when assembled together, the flange 251 of the front wall 243 and upper flange 248 b of the outer panel 248 of the side extension wall 222 and gear track 275 form an integral track 312 for indexing the position of the divider panel 238.

The cargo bed liner assembly 210 further includes a divider panel 238 and a positioning mechanism 230 for the divider panel 238, as previously described. The cargo bed liner assembly 210 also includes a tailgate panel fixedly attached to the tailgate (not shown) of the vehicle, as previously described.

The cargo bed liner assembly 210 with integral track 312 operates in a similar manner as previously described for the cargo bed liner assembly of FIG. 1. The guide means 257 for the side extension wall 222 extends therethrough the guide slot 244 in the flange 251 in the front wall 243 of the fixed side wall 218. The locking mechanism 256 is operated to position the side extension wall 222 relative to the fixed side wall 220. The divider panel 238 is positioned by depressing the handle 230 to retract the stabilizing block 302, moving the divider panel 238 along the track 312 to the desired position. Advantageously, the travel of the divider panel 238 within the integral track 312 is indexed, to avoid slipping or binding of the divider panel 238 as it is positioned. The handle 230 is released, such that the block 302 is fittingly retained within the indexing grooves 236 or 250.

Advantageously, the cargo bed liner assembly 210 is self-supporting, and is removably attached to the vehicle using an attaching means 310. An example of an attaching means 310 is a fastener such as a bolt, screw or hook or the like. Advantageously, this embodiment of the cargo bed liner assembly 210 does not utilize frame for support, and includes an integral track 312.

With reference to FIG. 10, a vehicle 320 such as a pick-up truck is provided with a cargo area 322 including a first side wall 324 and a second side wall 326 disposed in a generally transverse relationship. A floor 328 extends between the sidewalls 324, 326. The side walls 324, 326 each include a fixed side wall portion 330 and a side extension wall portion 332 which is slidably movable relative to the fixed side wall portion 330.

With continued reference to FIG. 21, the guide track includes a roller track portion 336 and a geared track portion 338 with gear teeth portions 338A which are in alignment with indexing grooves 340 which are provided along the vertical side walls. The gear teeth portions of the gear track 338 being in alignment with the vertical indexing grooves 340 allows debris that come in contact with the gear track 338 to fall downward through the indexing grooves 340 so that they do not inhibit movement of the gear wheels 342 of the support rod 344 supporting the movable divider panel 346.

Lights 350, including stop lights 352, turning signal lights 354, and tail lights 355, are mounted at the rear end of the side extension wall portions 332. The lights 350 are rendered operable when the side extension wall portions 332 are extended over top of the vehicle tailgate 356 and inoperable when the side extension wall portions 332 are pushed inward to a retracted position with the vehicle cargo area 322. A switch device 360, as best shown in FIG. 10A, is provided for activating and deactivating the tail lights 350 much like the dome lights of a vehicle are activated and deactivated by opening and closing a vehicle door. In order words, the switch device 360 has a plunger 362 movable relative to a base housing 363 which, when depressed, deactivates the secondary lights 350 and when released (as by extending the side extension wall portions), activates the secondary lights 350.

The vehicle 320 is also provided with exterior rear body panels 364 which are provided with primary stop/turn/tail lights 366 mounted at a rear end thereof. The primary lights 366 can be optionally deactivated upon activation of the secondary lights 350 when the side extension wall portions 332 are extended out over the tail gate 356. The switch device 360 is preferably positioned so that upon retracting the extendable side wall portion 332, the plunger 362 comes in contact with a stop member (not shown) to cause the plunger 352 to be depressed for deactivating the auxiliary lights 350.

With reference to FIG. 11, a vehicle cargo area 322 such as that described with reference to FIG. 10, can be provided with two or more movable divider panels 346 for providing increased versatility in dividing the cargo area 322. In addition, the movable divider panels 346 can be articulated to a horizontal position, as illustrated in phantom, such that the stabilizing block 102 can rest on the ledge formed by the guide track 334 to maintain the movable divider panel 346 in a horizontal position. The cargo area 322 can then be utilized in a two-tier loading configuration wherein articles can be stowed underneath the divider panels and on top of the divider panels 346.

With reference to FIG. 12, a sport utility-type vehicle 370 is shown. Although the cargo system of the present embodiment is shown utilized in combination with a sport utility-type vehicle, it should be understood that the cargo system herein described can also be utilized with vans and mini-vans and other rear hatchback-type vehicles such as stations wagons.
